Ichabod Spencer's "A Pastor's Sketches" is a great book. Spencer was a committed pastor, seeking to save souls, and his encounters with people needing the Lord and their various responses, is a great resource. This quotation struck a chord with me.
"I have often thought that a truly regenerate man cannot have any doubt about the total depravity of his heart. If he does not see THAT, he probably does not see his heart. And hence his repentance, his faith in Christ, his reliance upon the holy spirit will probably, all of them, be only deceptions."
